New engine issues

I got the engine fired up today and after fully warmed up i plugged off the port on the vaccum advance and the 2 vaccum ports on the edelbrock carb and set timing to 36º with timing light . With full time vaccum line hooked up to the vaccum advance it was reading 40º ? I didn't know if it made a difference since I have a mopar performance racing distributor with performance curv?
